Scottish First Minister Humza Yousaf is facing a serious challenge to his leadership after the Scottish Greens decided to support a motion of no-confidence against him. This decision comes in the wake of the termination of the power-sharing agreement between the Scottish National Party (SNP), led by Yousaf, and the Greens. The motion was initiated by Scottish Conservative leader Douglas Ross and is expected to be voted on as soon as next Wednesday.

The Greens’ withdrawal of support and potential alignment with the Conservatives, Labour, and Liberal Democrats in the vote put Yousaf’s position at risk, as the combined opposition could result in a 64-63 vote against him. The fissure in the coalition has been attributed to disagreements over several issues, including climate change targets and gender recognition reforms.

Complicating matters, the Greens have criticized the SNP’s focus, under Yousaf’s leadership, on independence over pressing governance issues such as housing and health. Additionally, Yousaf’s administration is clouded by the Operation Branchform investigation into the SNP’s finances.

If the motion passes, it would mark a significant shift in Scottish politics, challenging the SNP’s long-standing dominance and raising questions about the country’s political direction, especially regarding its environmental and independence strategies. The exact outcome will hinge on the vote of each Member of the Scottish Parliament (MSP), including potential swing votes like former SNP MSP Ash Regan, now affiliated with the Alba Party.
